January 5, 2010

Today we went over procedures for math class. This included a discussion on behavior expectations, attention to what is going on in class, and homework completion. We also talked about why these things are important if everyone is to learn to the best of his or her ability.

Periods 2 and 3
We went over the work that we ended last semester with—this was about a unit cube. This included its dimensions, the total area of all the faces, and how to determine if a net would make a cube when folded. This kind of thinking is difficult for some so we always have available grid paper so nets can be made and tested.
Following all of that everyone started on homework. This may be a repeat of things that we have done previously but I feel that the review is good for everyone.
Assignment: Period 2—p. 13, #15-18, #32.
Period 3—p. 10, #1-4, 15-16

Periods 4 and 5
We started Chapter 5 today. The title of Chapter 5 is “ Writing Linear Equations,” so that is what we will be doing. The first section deals with writing equations in slope-intercept form. The general formula for slope-intercept form is y = mx + b, where m stands for the slope and b stands for the y-intercept. This means that students need to be aware of some of the things that we did in Chapter 4, like identifying the y-intercept and finding the slope. We discussed how to do that again.
Students were also given a note-taking guide with step-by-step instructions on how to write an equation in slop-intercept form when given different parameters. This should prove to be helpful when doing homework.
We will be getting into how to write equations in point-slope form and standard form as we go through the chapter.
Assignment: p. 286, #3-9
